Chilly nights this weekend, then rain next week: Southern MS/AL/LA Weather Forecast – 1/18/24

Looking toward the weekend, it looks like we’ve got a brief cooldown coming, but certainly nothing like we just saw move through. This weekend, overnight lows will be down into the 20s across much of the region. The teens will be stuck to the north and 30s will be realized closer to the coast.

We start to warm things up next week again with another shot for showers and storms. And, looking at the latest data, it looks like a fair bit of rain will be possible with the chance for some severe weather, too.

The “National Blend of Models” from the NWS shows the biggest slug of rainfall closer to Houston, but parts of Louisiana, Mississippi and Alabama are looking at 3″ to 5″ of rain next week.

Looking at the CIPS Analogs, it shows the risk for the highest rainfall totals across parts of northern Louisiana. The map below, on the left, is the percentage of analogs that show more than 5″ of rain.

The map above, and on the right, shows the percent chance of at least one tornado. In this case the bullseye is across parts of northeast Texas and southeastern Louisiana.

The timeline on this rain would likely be between late Monday night and early Friday morning. It will likely come in a few batches, and won’t be a washout every day. But keep the umbrella handy next week and I’ll continue to try and hone in on when the biggest risk for severe weather might be. As of now, I’d estimated Thursday night.
